NASA satellites assist states in estimating abundance of key wildlife species

IMAGE: Mountain lions are the most common predator of mule deer in western North American ecosystems; their distribution, abundance, and population trends are closely tied to those of their prey (adult... view more  Credit: photo by D. Stoner LOGAN, UTAH, USA- Climate and land-use change are shrinking natural wildlife habitats around the world. Yet despite their importance to rural economies and natural ecosystems, remarkably little is…

Scientists reduced the weight of optics for satellite observation by 100...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (IEEE) published the article of the group of scientists of Samara National Research University. It describes the work on the creation and use of ultralight diffraction optics for obtaining high-resolution images. In this paper, the technology of manufacturing of a 256-layer diffraction harmonic lens and the algorithms for reconstructing the obtained images are…

NASA’s GPM passes over weakening Hurricane John

IMAGE: GPM flew over John at 2:59 a.m. EDT (0659 UTC) on Aug. 8. At that time John's maximum sustained wind speeds had started to decrease.
